CDRouter can display syslog messages using both the -decode option and the -pt (or -ptc) option. To create a syslog host, configure a staticHost entry for the syslog messages receiver that is configured on the device.

For example, if the device was configured to send syslog messages to 192.168.1.254, the following would be added to your local.conf file:

testvar staticHost 192.168.1.254

CDRouter will answer any ARP requests for staticHost entries, allowing the syslog message to be sent. With the -decode option, the syslog message will be displayed in the packet decode. With the -pt option, the syslog message will be logged.

NOTE: The IP address for a staticHost must be on the same subnet as the LAN configuration (testvar lanIp).
